CHALK-LINE HOLDER.

Specification of Letters Patent.

Patented Mar. *7, 1911.

Application filed September 2, 1910. Serial No. 580,185.

To @Il whom it may concern.'

Be it known that I, ConNnALUs P. HOOVER,

a citizen of the United States of America, residing at Hartford, in thecounty of Lyon and State or Kansas, have invented new and usefulImprovements in Chalk-Line Holders, of which the following is aspeciiication.

This invention relates to chalk line holders, the object ot' theinvention being to provide an improved article ot this character ontowhich the chalk line may be wound and to provide an effective chalkreceptacle constructed to permit the passage of the line thereto tochalk the same in an etlicient manner.

Another object of the invention is to provide the chalk receptacle witha retarding element over which the line is designed to travel, the saidretarding element through its engagement with the line offering theretoin its movement sutlicient resistance to prevent unwinding of the linetoo rapidly from the support, the said retarding element also acting asa regulating means to control. the feed of chalk onto the line.

another object of the invention is to provide telt or elastic likewashers at the apertured ends of the chalk receptacle and to constructthe said regulating and retarding element so as to bear against the saidelastic disks to hold them elo-sed against the ends of the receptacle toprevent the accidental discharge of the chalk from the said aperturedend.

ln the drawing, forming a portion of this specification and in whichlike numerals of reference indicate similar parts in the several viewsFigure 1 is a perspective view of my improved line holder. Fig 2 i? alongitudinal section therethrough.

The line holder comprises a substantially spool-like member 1 which isprovided with a longitudinal passage 2, as shown. The member 1 isconstructed to permit the cord 3 to be wound thereon as shownparticularly in Fig. l of the drawing. The member 1 is 'provided at itsends with heads or guards t,

each of which being provided with a kerf 5 tor a purpose to behereinafter described.

A. receptacle (3 is mounted in the passage 2 in the member 1, and asillustrated, it is provided at one end with a xed plug 7 and at itsopposite end with a removable plug 8. The plugs are provided withalining passages 9, as shown. A combined regulating and retardingelement 10 is located in the receptacle 6 and as illustrated, itconsists preferably of a spring-like member which is formed to providethe looped end portions 11 and the intermediate substantially U-shapedportions 12. rlhe construction of the portions 12 is such that radialretarding arms 13 are provided and disposed in line with the passages 9in the plugs of the receptacle. An apertured felt or suitable elasticdisk 14 bears against the inner end of the plug 7 and a similar disk 15bears against the inner end of the plug 8. The elasticity of theretarding and regulating element is such that the ends 1Q bear againstthe disks 14 and 15 to hold them tight against the plugs 7 and 8 toprevent the chalk from lodging behind the disks and Jfrom escaping intothe passages 9. The cord 3, as shown in Fig. 1 of the drawing, extendsthrough the kerf- 5 in one head of the support 1 and through the plugs 7and S and the receptacle 6. The tree terminal ot the cord is formed toprovide a loop 1G, and as illustrated, the free terminal of the cord maybe confined in the kerlt 5 in the opposite head ot the support 1 to holdthe cord against unwinding when the holder is not in use. A' ring 17 ismounted on the cord and is disposed inwardly of one of the heads 4 ofthe holder so as to permit the convenient manipulation of the cord whenit is desired to remove the same from the kerf 5 in that head adjacentto the plug S. The cord may be threaded through one or more of theintermediate loops of the said retarding and regulating element soas toprevent the superiiuous appearance of the chalk to the line. The arms 13of the intermediate loops also serve to bear with sufficient frictionagainst the cord to prevent atoo rapid unwinding of the same from theholder.

l claim:

1. A chalk line holder comprising a supporting member for the line, theline having one of its terminal ends extending through the supportingmember, the said supporting member having a chamber formed thereinthrough which the line can be drawn, apertured closures at the ends ofthe chamber, apertured elastic disks fitting against the apertured endsof the chamber, and a retarding element of springy material rotating inthe chamber and frictionally contacting with the line and having its endportions bearing against the elastic disks to hold them against the saidapertured ends of the chambei'.

2. A ehaik line holder Comprising a spoollike supporting member for theline, the said member having a Chalk containing chamber therein,apertured plugs closing the ends of the chamber, a line carried by thesupport and having one of its end portions extended through the saidapeitui'ed plugs and through the chamber, the said supporting l memberhaving retaining keifs therein, the i said line having portionsremoiahly enl gag-ed 1n the kerfs to prevent unwmding of t 1e line fromthe supporting member.

in testimony whereof I ai'ix my signatui'e in presence of two Witnesses.
